Question
Cost of a gadget is Rs. (10n + 150). It is marked up by
60% and sold after deducting Rs. (5n + 100) as discount. If a profit of Rs. 1,200 is made, find the value of 'n'.Solution
ATQ,
Selling price = (16n + 240) - (5n + 100) = Rs. (11n + 140)
Profit = (11n + 140) - (10n + 150) = Rs. (n - 10)
So, n - 10 = 1,200
Or, n = 1,210
